“…Heterobimetallic thiocarboxylate complexes, [(PPh 3 )Cu(S-COPh) 3 Zn(PPh 3 )] (1) and [(PPh 3 ) 2 Ag(SCOPh) 2 Zn (SCOPh)(0.5H 2 O)] (2) were synthesized using the methods reported elsewhere. 50,51 Synthesis of bulk ZnS/CuS and ZnS/Ag 2 S alloys The complexes were pyrolyzed under dry N 2 atmosphere in a muffle furnace at 350 C. The solid residue obtained was washed successively with ethanol, carbon disulde and diethyl ether. The residue aer drying under vacuum (0.1 mm/Hg, 3 h) was analyzed by SEM (ESEM Quanta), PXRD (d8, Bruker) and XPS (Thermoscher).…”

Heterobimetallic complexes [(PPh 3 )Cu(SCOPh) 3 Zn(PPh 3 )] and [(PPh 3 ) 2 Ag(SCOPh) 2 Zn(SCOPh)(0.5H 2 O)] were used as single molecular sources for the syntheses of ternary compounds. These complexes upon pyrolysis at 350 C in the solid state yielded ZnS/CuS and ZnS/Ag 2 S alloys respectively. In oleylamine solution decomposition of the complexes took place at 165 C only leading to the formation of the corresponding sulfide nanoparticles. The bulk sulfide materials have been characterized by SEM-EDX, XPS and powder X-ray diffraction techniques. The nanoparticles have been characterized by EDS-elemental mapping and HRTEM.

“…31 The Zn-O bond length is 2.38(3) Å, which is similar to the previously reported case. 32 In the framework of MCCF-22, three apexes of each P1 cluster are connected with three adjacent P1 clusters via the corner-sharing mode, and the remaining one is connected with a Zn 2+ ion. The connection mode results in the formation of a μ 4 -P1 unit (Fig.…”

Six new compounds of formula [M(TBn) 2 L] [TBn: thiobenzoato; M: Pd II , Zn II , Cd II ; L: 2,2′-bipyridine (bpy), 1,10phenanthroline (phen), 1,2-di-(4-pyridil)-ethylene (bpe), neocuproine (neo), adenine (ade)] are obtained by the reaction of M(CH 3 COO) 2 ·2H 2 O with thiobenzoic acid and N-heterocyclic ligands. The use of chelating ligands and adenine leads to monomeric compounds: [Pd(TBn) 2 (bpy)] (PdBPY), [Pd(TBn) 2 (phen)] (PdPHEN), [Zn(TBn) 2 (neo)] (ZnNEO), [Cd(TBn) 2 (neo)] (CdNEO), and [Cd(TBn) 2 (ade)(CH 3 OH)] (CdADE). In these compounds, the metal is bonded to the sulfur atoms of two TBn anions, while the remaining coordination positions are completed by the donor atoms of the ancillary ligands. The bridging capability of the bpe ligand gives rise to the polymeric [Cd(TBn) 2 (μ-bpe)] n [a]This section first describes the crystal structures of the metalorganic precursors, as these data will support the discussion regarding the formation of carbonaceous composites of metal and metal-sulfide nanoparticles (M/C and MS/C, respectively). Prior to the dry thermolysis experiments, a subsection devoted to preliminary thermogravimetric analyses is presented, in which the decomposition mechanism and optimum treatment temperature ranges will be set. Thereafter, results on the dry thermolysis experiments are thoroughly discussed, detailing the microstructures and particle sizes obtained in each case, to end up with the influence of the thermal treatment parameters. Crystal Structure of PrecursorsAt first glance, the coordination sphere of these complexes (Figures 1 and 2) involves two sulfur-bonded thiobenzoate ligands, with the remaining coordination positions being occupied by two nitrogen donor atoms from a chelating N,N′-heterocyclic Eur.
